在javascript中获取字符串数组中对象的所有叶节点属性的函数

const getBranches = (data, prefix='') => {
  if (typeof(data) !== 'object') {
    return prefix.substr(1)
  }
  return Object.entries(data).flatMap(([k, v]) => getBranches(v, [...prefix.split('.'), k].join('.')))

  }

  const data = {
    "message": "string",
    "data1": {
      "Output1": {
        "leaf1": "abc",
        "Leaf2": "123"
      }
    },
    "data2": {
      "Output2": {
        "leaf3": "abc",
        "leaf4": "123"
      }
    }
  }


console.log(getBranches(data))
